If you mean codebase complexity and team size... then yes... types is more helpful with that. But in a small team with a small codebase you don't need types to do really well. I find types helped a lot when multiple teams were responsible for different domain spaces inside different components of a Rails app. I never saw the same advantage in codebases that are much smaller with fewer people.

If you can keep everything in your head, types can feel superfluous. Large projects make that nigh impossible.
